The correct answer is option-D
The fossil record shows species suddenly appearing and disappearing. When one species goes extinct, another one usually takes its place. It provides with the snapshots of the past. It shows the changes over the past four billion years. It maybe unclear at parts but it does provide evidence that life is old and over time has changed. By studying fossil record the relation of different plants and animals can be figured out and it also tells us how old life is on earth. We can learn about extinct species and find out the reasons as well behind there extinction.

1. The royal family was marrying within the family (mostly between cousins) hence increasing the chances for which the offspring will be homozygous recessive for the gene (factor VIII) that codes for hemophilia (This can be shown by Mendel's model of crossing the first and second filial generations of plants. This generated more recessive traits in the population). This culture was an attempt to ensure the wealth of the family remains in the dynasty. However, the genetic repercussions have made the Royal family have allowed marrying outside the family.
2. An individual with hemophilia is referred to as a hemophiliac individual. Individuals with a recessive allele for the conditions are carriers and can produce offspring with hemophilia if they breed with another carrier or a hemophiliac individual,
Answer:
Hemostasis is the response that occurs when there is blood loss and the barrier of the skin has been compromised.
Explanation:
Hemostasis involves the process of blood clotting that ends in the formation of a clot, capable of stopping blood loss from an injury.
When a superficial wound occurs, there is an injury to the skin —with involvement of the dermal barrier— and the rupture of blood vessels produces bleeding. <u>Hemostasis helps to stop blood loss, so that wound healing and restoration of the skin barrier can begin</u>.
